posed of a number of units of the usual I6" ticulated type made of strips of strawboard, or equivalent material, and boards or flats having projections which e'nga tain members of the filler units to hold the same in operative position. Such flats are placed both between. successive filler units and above the-uppermost unit and below the.

lowermost unit. The intermediate flats have projections which engage the -units above and below them 'whilethetop and bottom the angles of theslits isbent oridown the projections thus: formed will 1n. osrtion to engage thezintersectionsr eitheerr units and hold them sition.. p

in proper operative po formation of the projections abovadescribeil after the cross slits in thexflat: have been made and the material has been properly scored or grooved to facilitate the deflectionofthe portions which form thepro ections,

and has for its object to provide an apparatus by which all the projections of a'flat may be formed at one operation and 'wifliout damaging the flat, which is necessarily made of straw-board, or other cheap-material;

A further object is to provide apparratus which may be readily adjusted to vary *jections.

Said blocks 21 are disposed in offset relation to the several projecting members 18, as shown in Fig. 1,'for a purpose which herein: after appear. 23 indicates triangular spacin'g blocks employed wherever necessary to fill up the frame, and 24 indicates triangular projecting members which are employe% 'at 1g.

the margins of the frame, as shown in 1. 25 indicates stopswhioh are provided on the frame 15 at two of its margins, as shown in Fig. 1. Said stops serve not only toposiand 24. The frame 26 is also provided with recesses 30 which receive the stops 25 for registration purposes.

As best shown in Fig. 3, the frames 15 and 26 are adapted to be secured respec-' tively to supports 31-32 inany suitable way as by-bolts 3435- passing through ears 36-37 provided on said frames. One

of said supports is made movable so that the frame carried by it may be moved into en'- gagement with the oppositeframe. When this is done the projecting members '18 and :24 enter the corresponding recesses in the plate 28.

The fiat to be operated upon, which is shown in dotted lines at 38 in'Fig. 3, after first beingprovided with the cross slits hereinbefore referred to, is placed upon the projecting members 1824, two of its margins bearing against the stops 25. The two frames are then brought together, whereupon the projecting members are forced through the flat, deflecting the angular portions formed by the cross slits so that such angular portions are 'caused to project in the manner shown at 39 in Fig. 10. It will be noted that with this arrangement the proections would be formed at one surface only termediate flats in which the projections ex-' of the fiat, as is necemary for. the upper and lower flats in an egg case. For making intend from both surfaces of the flat, the

' frame28 is provided with projecting members similar to the members 18 and 24, which are placed in the positions indicated by dotted lines in Fig. 2. As illustrated in dotted lines in Fig; 3, such-projections, when the ,two frames are brought together, enter the recesses provided by using the thin spacing blocks 21, and consequently the-projecting members carried by one. frame deflect cermin of the slit portions of the flat upward, while the projecting members carried by the other frame bend certain other of the slit portions of the flat downward.

In Fig. 11 I have shown a frame 40in .which the several projecting members are formed integral with the base of the frame in which they are carried, this being accomplished by cutting away the material between the several projecting members. This construction may be employed where it is not desirable to change the position of the projections.

In Fig. 13 -I have shown a cotiperating frame 41 adapted to be employed in connection with either of the frames shown in Fig. 1 or Fig. 11. a

In Fig. 12 Ihave shown a further modislightly beyond .the' ends of the projecting.-

members' by springs 4647. frames are brought together the. plates. 42-43 move toward their respective frames, the projecting members extending through. them. The object of this construction is to.

provide supports at both sides of the flat to.

.be operated upon so that the flat is not 'apt to -be torn and the projections formed aremore sharply creased when. bent so that they retain their angular position better than 'where the supporting plates are not used.

In Fig. 14 I have shown a similar form of apparatus designed for making the to and bottom flats, in which case only a single supporting plate 43 need be employed, since the projections on the fiat extend from one surface thereof only. v

I have not shown any mechanism for actuating the frames to move them toward and from each other, as any suitable mechanism for that purpose may be employed, and such mechanism forms no part of'my present invention.
